 If your application was built using the |NCS|, you must define partitions using :ref:`partition_manager`.
 The built-in partition definitions can be found in the :file:`nrf/subsys/partition_manager` folder, and the file names start with ``pm.yml``.
 The files that have ``external_flash`` as their region support storing partitions in the external flash.

 The Modem library, which runs on the application core, shares an area of RAM memory with the nRF91 Series modem core.
 During the initialization, the Modem library accepts the boundaries of this area of RAM and configures the communication with the modem core accordingly.
